PAPER-FILING CABINET.

SPECIFICATION forming part of Letters Patent No. 427,998, dated May 13, 1890.

Application filed August 20,1889. Serial No. 321,386. (No model.)

To @ZZ whom t may concern.-

Be it known that I, MAJOR ROMEYN JEW- ELL, of Rochester, in the county of lVIonroe and State of New York, have invented certain Improvements in Paper-Filing Cabinets, of which the following is a specification.

This invention relates to cabinets which contain a series of Iile-boxes, trays, or receptacles removable independently at the front; and it consists in an improved mechanism whereby the entire series of boxes maybe instantly locked in position within the case or instantly unlocked at will.

The invention consists, essentially, in the combination of a slide-operatin g bar mounted in the cabinet and connected witha lock and with a vertically-movable frame having hooks or teeth to engage the respective boxes or reeeptacles.

In the accompanying drawings, Figure 1 is a vertical section from front to rear through a cabinet provided with my improvements in its preferred form, the parts being shown in their locked position. Fig. 2 is an outline view showing1 in perspective the essential parts of the mechanism, the parts being in the position which they occupy when the boxes are unlocked. Fig. 3 is a perspective view of the intermediate lever and its support. Figs. 4 and 5 are elevationsshowing modifications of the locking devices.

Referring` to Figs. 1, 2, and 3, A represents the cabinet, and B B a series of boxes or receptacles mounted in and adapted to be withdrawn from the front of the cabinet in the ordinary manner. The cabinet and the receptacles may be of any ordinary or approved construction, provided, only, the receptacles are adapted to extend backward to a point near the rear wall, wherethey are each to be provided, as shown, with a hole or shoulder l) to receive the locking-lips. v

In carrying myinvention into effeetI mount in the back of the case, preferably in guides on the rear wall, a vertical locking-frame C, composed of a series of vertical bars c, provided with downwardlyfprojecting lips or hooks c, and suitably connected by cross-bars c2, so that the frame may rise and fall bodily. The hooks c are suitably formed and their carrying-bars suitably located to admit of 'the hooks engaging the holes or shoulders of the respective boxes when the frame is lowered. By lifting the frame the hooks are all disengaged and the entire series of boxes released.

For the purpose of operating the frame I mount in the base of thc cabinet in suitable guides a bar D, arranged to slide forward and backward, with its forward end projected outside of the case to serve as a handle. IVithin the case, near the front, the bar is provided with a notch d to receive the bolt e of an ordinary key-lock E, which is applied to the cabinet in such position that it may be operated by a key from the outside. A lever- F is pivoted ina suitable bearing G on across bar Il or equivalent support and bears at one end in or beneath one of the vertical bars of the locking-traine, while at the opposite end it is curved upward through an opening in the sliding bar D. Vhen, therefore, the bar D is drawn forward, it acts through the lever F to lift the locking-frame and release the iileboxes, while on being thrust inward the slide operates, on the contrary, to lower the locking-frame and secure the boxes.

In order to prevent the locking-frame from being jarred out of position to release the box or of its being clandestinely operated in any manner, the vertical bar C, on which the lever operates,is formed with a horizontal shoulder or offset c3, (sce Figs. 1 and 2,) over which the inner end of the sliding bar D engages when it. is thrust inward, as shown in Fig. l, the locking-frame being thus held down firmly in place by the sliding bar, which is in turn held to its place by the locking-bolt.

The bearing for the lever F may be of any suitable-form; but I recommend the bearing such as shown in Fig. 3,1ecessed and notched in the upper side to admit of the lever being dropped into place therein, the lever being provided, as shown, with trunnionsj The lever F may be modied in form. In Fig. 4 its rear end is inserted through the locking-frame, s0 as to carry the same positively upward and downward, while its front end is passed vertically through a hole in the sliding bar D and provided with inclined surfaces f2 and f3, on which the bar acts as it is IOO moved to and fro, so as to compel the motions of the lever in reverse directions.

In Fig. 5 the lever is of angular form, with one extremity connected to the sliding bar 5 and the other inserted through a hole in the locking-frame.

It will be observed that in each form of my locking mechanism the operating-bar is ar ranged to Slide forward and backward and to connected to the locking-frame to move the same vertically.

Having thus described my invention, what I claim isl. The cabinet and lthe boxes removable at 15 its front, in combination with the verticallymovable lookin gf rame en gagin g the boxes in
